Location of Borobudur–Pawon–Mendut in one straight line

Approximately 40 kilometers (25 mi) northwest of Yogyakarta, Borobudur is located in an elevated area between two twin volcanoes, Sundoro-Sumbing and Merbabu-Merapi, and two rivers, the Progo and the Elo. According to local myth, the area known as Kedu Plain is a Javanese 'sacred' place and has been dubbed 'the garden of Java' due to its high agricultural fertility. Besides Borobudur, there are other Buddhist and Hindu temples in the area, including the Prambanan temples compound. During the restoration in the early 1900s, it was discovered that three Buddhist temples in the region, Borobudur, Pawon and Mendut, are lined in one straight line position. It might be accidental, but the temples' alignment is in conjunction with a native folk tale that a long time ago, there was a brick-paved road from Borobudur to Mendut with walls on both sides. The three temples (Borobudur–Pawon–Mendut) have similar architecture and ornamentation derived from the same time period, which suggests that ritual relationship between the three temples, in order to have formed a sacred unity, must have existed, although exact ritual process is yet unknown.
Unlike other temples, which were built on a flat surface, Borobudur was built on a bedrock hill, 265 m (869 ft) above sea level and 15 m (49 ft) above the floor of the dried-out paleolake. The lake's existence was the subject of intense discussion among archaeologists in the 20th century; Borobudur was thought to have been built on a lake shore or even floated on a lake. In 1931, a Dutch artist and a scholar of Hindu and Buddhist architecture, W.O.J. Nieuwenkamp, developed a theory that Kedu Plain was once a lake and Borobudur initially represented a lotus flower floating on the lake. Lotus flowers are found in almost every Buddhist work of art, often serving as a throne for buddhas and base for stupas. The architecture of Borobudur itself suggests a lotus depiction, in which Buddha postures in Borobudur symbolize the Lotus Sutra, mostly found in many Mahayana Buddhism (a school of Buddhism widely spread in the east Asia region) texts. Three circular platforms on the top are also thought to represent a lotus leaf. Nieuwenkamp's theory, however, was contested by many archaeologists because the natural environment surrounding the monument is a dry land.
Geologists, on the other hand, support Nieuwenkamp's view, pointing out clay sediments found near the site. A study of stratigraphy, sediment and pollen samples conducted in 2000 supports the existence of a paleolake environment near Borobudur, which tends to confirm Nieuwenkamp's theory. The lake area fluctuated with time and the study also proves that Borobudur was near the lake shore c. 13th and 14th centuries. River flows and volcanic activities shape the surrounding landscape, including the lake. One of the most active volcanoes in Indonesia, Mount Merapi, is in the direct vicinity of Borobudur and has been very active since the Pleistocene.
